The international team led by astronomers from Peking University in China and from the University of Arizona have discovered a supermassive black hole.
The recently discovered black hole is 12 billion times the mass of our
sun pumping out a million billion times the energy of our Sun. They
believe it may have been formed after the first stars and galaxies
emerged after the Big Bang gave birth to our universe.

Recent discovery has puzzled the scientist as 'How could something so massive and luminous form so early in the universe, only 900 million years after the Big Bang?' Scientists cannot explain how the newly found black hole grew so quickly, Reuters has written.

"How can a quasar so luminous, and a black hole so massive, form so early in the history of the universe, at an era soon after the earliest stars and galaxies have just emerged?," Xiaohui Fan, Regents' Professor of Astronomy at the UA's Steward Observatory said as quoted by Science Daily.
Scientists said this supermassive black hole was formed about 900 million years after the Big Bang.
